When I first got my vtube, the atomizers and carts screwed in nicely, with no play or anything. A few days later, I could wiggle the carts back and forth as I tightened them, pretty much all the way down. Does this mean it is cross threaded, or did something else come loose? 
If it is cross-threaded, is it "contagious"?
I am about to get a provari. I am worried that if I screw in a cart into the vtube, which might mess up the threads, then put it in the provari, it will mess up the provari threads. Is this possible?
